Abstract

A hinge joint for orthopedic knee braces that enable a wearer or medical professional to quickly and efficiently adjust the lateral corrective force placed on the knee joint so as to apply the force at heel strike (full extension) when it is most needed, but will relax the loading during flexion. The hinge joint, for use in a three point pressure system of a knee brace, has a first part that is connectable to a femoral arm of a knee brace and a second part that is mounted to be able to telescope out of the first part as the leg is extended and to telescope back into the first part as the leg flexes.

Description

CROSS REFERENCE TO RELATED APPLICATION
This application is a § 371 of International Application No. PCT/US2014/017263, filed Feb. 20, 2014 and non-provisional conversion of provisional application 61/792,099.
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is directed to hinge joints for orthopedic knee braces, particularly for braces that enable a wearer or medical professional to quickly and efficiently adjust the lateral corrective force placed on the knee joint.
Description of Related Art
A knee brace of the type for which the hinge joint of the present application is intended is disclosed in U.S. Pat. No. 6,413,232. Correction of the lateral corrective force placed on the knee joint via a three point pressure system is obtained in this brace by the provision of a spring-loaded ratchet mechanism that features a series of interlocking teeth that allows for the horizontal displacement of the condyle pad support. However, this is a static device that once adjusted, is the same at all angles of flexion. As a result, this joint increases the medial/lateral displacement throughout the range of motion.
Similarly, in the knee brace of U.S. Pat. No. 6,981,957, which utilizes a pair of hinges, one of which provides for movement in a posterior-anterior plane and the other which provides for movement in a medial-lateral plane, pressure is always applied even when sitting down.
SUMMARY OF THE INVENTION
Therefore, it is a primary object of the present invention to provide a joint for orthopedic knee braces that enable a wearer or medical professional to quickly and efficiently adjust the lateral corrective force placed on the knee joint so as to apply the force at heel strike (full extension) when it is most needed, but will relax the loading during flexion.
This object is achieved by providing a joint that can add correction to a three point pressure system of a knee brace by telescoping the condyle out as the leg is extended and in as the leg flexes. According to a preferred form of the joint, the joint is formed of a condyle cam part and condyle driver part which are move relative to each other as leg flexes and extends.

FIGS. 9 & 10 are views of the joint of the present invention connecting a tibial arm of a knee brace to a femoral arm of a knee brace in full extension and full flexion, respectively.
 DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a knee brace equipped with a joint according to the present invention for purposes of illustrating the three point pressure system adjusted by the joint of the present invention. As is shown, two force points A, C are created at the medial (interior) side of the leg by femoral and tibial crosspieces or straps with a third force point B occurring at the lateral side joint which acts on the lateral condyle of the knee. Increasing and decreasing loading at the lateral condyle changes the angulation of the leg with the goal of minimizing the pressure on the compromised compartment of the leg D during full extension/heel strike.
FIGS. 2 & 3 show the inventive joint J connecting a femoral arm F to a Tibial arm T of the knee brace shown in FIG. 1. As can be seen from FIGS. 4-8, the hinge joint of the present invention is comprised of a rivet 1, a return spring 2, a condyle cam 3, a condyle cam driver 4, a hinge cap 5 and attaching screws 6. The interior of condyle cam 3 and a condyle cam, driver 4 face each other and are provided with ramps 3 a, 4 a respectively.
The condyle cam driver 4 is attached to the femoral arm F with two screws 6 and rotates around the center boss 5 a on the hinge cap 5. During extension of the hinge joint J, the condyle cam driver 4 rotates with the femoral arm F of the joint J. As condyle cam driver 4 rotates the three ramps 4 a slide against the opposing ramps 3 a on the condyle cam 3. This movement of the ramps over each other forces the condyle cam 3 to extend (project) against the lateral side of the knee condyle while compressing the return spring 2. Rotation of condyle cam 3 is prevented by the two protrusions 3 b that engage into complementarily shaped slots 5 b in the hinge cap 5.
During flexion of the joint J, the return spring 2 forces condyle cam 3 to slide down the ramps 4 a in cam driver 4, thereby allowing condyle cam 3 to retract into cam driver 4 with a resultant decreasing of the lateral load on the knee during flexion, being fully retracted at full flexion. On the other hand, at full extension, the condyle cam is fully extended.
Thus, the hinge joint of the present invention is able dynamically change the pressure applied to the lateral side of the knee condyle with changes in the angulation of the leg so that, at heel strike (or full extension; FIG. 9), the pressure on the compromised compartment of the leg is minimized. That is, the condyle cam applies force at heel strike when it is needed most and relaxes during flexion. Thus, at full extension, the condyle cam is fully extended as shown at E in FIG. 9 while at full flexion, the condyle cam 3 is fully retracted as shown at F in FIG. 10.
It should be appreciated that the brace shown in FIG. 1 is only one of the various types of knee braces that exist and those of ordinary skill will appreciate that the hinge joint the present invention can be incorporated into many other types of braces than that shown. Likewise, while the particular embodiment shown has three ramps 3 a, 4 a, other numbers of ramps can be used, the slopes thereof being adjusted accordingly. Similarly, while the particular embodiment shown is contemplated for use as a so-called Townsend motion joint (see, e.g., U.S. Pat. No. 5,259,832), the invention is easily adaptable for use as a geared polycentric or single pivot joint.
